PXB 7.5M BETATRON | JME ADVANCED INSPECTION SYSTEMS

The PXB7.5M portable X-Ray Betatron is designed to produce high energy ionising radiation for industrial radiographic non-destructive testing.

The PXB7.5M contains no moving parts (excluding cooling fan) and no circulating liquids, radiation outside the main beam are low, so safe working distances are moderate. After demarcation of dose rate boundaries, the betatron may be used at external sites or in fabrication workshops with little or no additional screening.

The PXB7.5M is recommended for radiographic testing of weld joints and castings with a steel thickness of 50 to 300mm, concrete and other materials from 200 to 1200mm.

The irradiation field equals 250mm x 250mm @ 1M focal distance. In operation the PXB7.5M has no need for compensating filters that improves the uniformity of the radiation field.

The PXB7.5M is far less costly than other NDT accelerators such as 'Linacs'.

The PXB7.5M can replace cobalt isotope gamma sources which may not give acceptable quality and require costly periodic replenishment.

Compared to cobalt, the Betatron's shot time is drastically reduced and the extremely small focal spot size provides a sharper, higher quality radiograph, thus increasing production rate and profit.

APPLICATIONS:

JME’s range of Betatron systems have been supplied for a wide variety of applications within many sectors of the NDT industry. Examples of the work we have previously supplied systems for include but are not limited to the inspection of Large forgings, castings, valves, beams, ships hulls, pressure vessels, engine blocks, thick welds, composites, reinforced concrete buildings, bridges and cargo/security scanning solutions.

Less efficient power conversion

BETATRON/CYCLOTRON

A Betatron Portable X-Ray System is a type of Cyclic Particle Accelerator, in some areas of the world, these systems are also referred to as a Cyclotron X-Ray System. Betatron systems include a Torus-shaped vacuum tube which house electrons as they are accelerated around a circular path using alternating current, and then ejected at a specific target once they have achieved the required velocity.

The main difference between the Betatron and Cyclotron systems is that the Cyclotron uses magnetic fields to bend the particles into a circular path and a pulsing electromagnetic field to increase the speed of the particles. The Betatron systems only use magnetic fields to increase the speed of particles.
